I have looked but for some reason the serial number on my engine is not coming up. It is the mercruiser tag located above the starter on the starboard side. The boat and I believe engine is a 1993 rinker with a 350 mercusier engine. The tag serial number states " D842217" I am curious as to weither it is a 350. or 350 mag or what because it is noticably larger than the 350 that was in my sea ray. Any info or links will be appreciated....Thanks
